What it is
A domain research server over registration data — active, aged, expiring, deleted and newly registered names — with availability, WHOIS, DNS, pricing, trend and marketplace lookups alongside, plus a small stateful layer for monitors and preferences.
Requirements
Nothing to start: without DOMAINKITS_API_KEY the server runs on a guest quota, either locally over stdio through the npm package or by pointing a Streamable HTTP client at https://api.domainkits.com/v1/mcp. A key raises the tier. The stateful tools are different — monitors, preferences and strategy need a registered account with memory explicitly enabled, and they store nothing until it is. How many monitors you may keep and how often each tool group may be called follow the tier, which the usage tool reports.
Setup effort
One command — claude mcp add --transport http domainkits https://api.domainkits.com/v1/mcp
